HINGE Original Filed Oct. 15, 1956 4 Sheets-Sheet 4 [nvenior j/ \v .ZTeYP/ 0,30%)? A iiorneys Patented May 24, 1938 UNITED STATES- PATEiii QFFIQE Application October 15, 1936, Serial No. 105,762 Renewed October 11, 1937 2 Claims.

The present invention relates to new and useful improvements in hinges particularly for automobile doors and has for its primary object to pro- Vide, in a manner as hereinafter set forth, a novel construction, combination and arrangement of parts through the medium of which the hinge will be concealed from view when the door is in closed position and which, when said door is opened, will automatically shift same in a horizontal plane away from the casing on which it is mounted to allow for the bulge or curvature of the body of the vehicle.

Other objects of the invention are to provide a concealed hinge of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured and installed at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:--

Figure 1 is a View in front elevation of a pair of hinges constructed in accordance with the present invention, showing the door in open position.

Fig. 2 is a detail view in perspective of the door supporting member.

Fig. 3 is a view in horizontal section, taken substantially on the line 33 of Fig. 5.

Fig. 4 is a view in horizontal section, substantially similar to Fig. 3, but showing the door in open position.

Fig. 5 is an elevational view of the invention with parts omitted, showing portions of the door and body in vertical section.

Fig. 6 is a vertical sectional view, taken substantially on the line 6-6 of Fig. 3.

Fig. 7 is a detail view in perspective of the door shifting crank.

Fig. 8 is a fragmentary view in elevation, looking at the hingedend of the door, showing the supporting member and toggle in cross section.

Fig. 9 is a detail view in perspective of the toggle.

Fig. 10 is a view in horizontal section, taken substantially on the line IIl-I0 of Fig. 6, the

moving parts being omitted.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a plate I which is mounted horizontally at an intermediate point in a chamber 2 in the body 3 of the vehicle.

As shown to advantage in Fig. 1 of the drawings, the body 3 of the automobile is bulged or curved from top to bottom. The plate I has formed therein a cam slot 4 which is preferably of substantially the shape shown to advantage in Figs. 3 and 4 of the drawings.

The door 5 of the vehicle has formed therein a pocket or the like 6 for slidably receiving the free end portion of an angular supporting member I which is hingedly secured at one end, as at 8, in the chamber 2. The door supporting member I has formed therein a slot 9 which accommodates a stop bolt II) which is mounted in the door 5 and which traverses the pocket 6. On the hinged end portion of the door supporting member I is a guide I I, the purpose of which will be presently set forth.

It will be observed that the member I is hingedly mounted in the chamber 2 above the plate I.

The reference numeral I2 designates generally a toggle which is mounted below the plate I in the chamber 2 and which comprises hingedly connected sections I3 and I4. One end of the toggle I2 is hingedly connected to the vehicle body 3 in the chamber 2 and the other end of said toggle is hingedly connected to the door 5, as at I5. The section or link I4 of the toggle I2 has formed thereon a vertical bearing I6 in which the lower end portion of a door shifting crank I I is journalled. The crank I! travels in the cam slot 6 and has its upper portion rotatably and slidably engaged in the guide II of the member I.

The reference numeral I8 designates a slotted cam plate which is mounted in the upper portion of the chamber 2 and which is substantially similar to the plate I. The upper end portions of the crank l'l travels in the slot of the plate I8. It will be observed that the plates I and I8 are so formed as to include fingers or extensions I9 which project from the chamber 2. The hinged end of the door '5 is recessed, as at 20, to accommodate these fingers I9.

As shown in Fig. 1 of the drawings, two of the hinge structures constituting the present invention may be used for each door. The door is swung to open and closed positions on the supporting members I. It may be well to here state that the cranks I'l constitute means for connecting the toggles I2 to the members I for actuation thereby. As the door is opened the members I cause the cranks H to travel in the cam slots 4 of the plates i and I 8 from the position shown in Fig. 3 of the drawings to substantially the position shown in Fig. 4, depending on the extent to which the door is opened, thereby actuating the toggles l2 in a manner to shift the door outwardly on said members I to allow for the vertical curve or bulge of the sides of the automobile body 3. Of course, when the door is closed, the foregoing operation is reversed.

It is believed that the many advantages of a concealed hinge constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall Within the scope of the invention as claimed.

What is claimed is:-

1. A door hinge comprising a supporting member pivotally mounted on a casing and slidably connected to a door, a plate mounted on the casing and having a cam slot therein, a toggle pivotally connected at one end to the casing and at its other end to the door, and a crank member operable in the cam slot and operatively connected to the toggle and the supporting member, said crank member constituting means for connecting the toggle to the supporting member for actuation thereby for shifting the door on said supporting member when said door is opened or closed.

2. A hinge comprising, in combination, an angular supporting memb'erpivotally mounted for swinging movement on a casing, a door slidably mounted on said supporting member, an elongated guide on the supporting member, vertically spaced plates mounted in the casing and having cam slots therein, a toggle having one end pivotally connected to the door and its other end pivotally connected to the casing, a bearing on said toggle, and a crank member operable in the cam slots and having one end portion journalled in the bearing and its other end portion rotatably and slidably mounted in the guide, said crank member constituting means for connecting the toggle to the supporting member for actuation thereby for shifting the door on said supporting member when said door is swung to open or closed position.
